APPARATUS FOR FORClNG BEER.

SPECIFICATION forming part of Letters Patent No. 355,464, dated January4, 1887.

Application filed November 2 1885. Serial No. 181,700. (No model.)

To aZZ whom it may concern.-

Be it known that I, J noon N ATTER, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia. and State ofPennsylvania, have invented a new and useful Improvement in Apparatusfor Forcing Beer, of which the following is a specification.

My invention relates to beer-forcing appatus; and the object of myimprovement is to force beer from a keg or barrel by air, and, at will,force the beer from the pipes back to the keg or barrel,so that a keg orbarrel once tapped will have air on' the beer at all times until all thebeer is drawn from the keg or barrel.

The first part of my invention relates to a reversing faucet. The secondpart relates to an improved check-valve; and the first part of theimprovement consists in the combination, with an air-pump and anair-accumulator, of pipes, cheek-valves, and a two-way or reversingfaucet.

The second part of my improvement consists in the combination of pipes,valve-chambers, and a rubber tubing, said tubing being construeted andapplied to the pipes in a peculiar manner to form a cheek-valve, all aswill be hereinafter described, referring to the annexed drawings, makinga part of this specification, in which Figure l is a plan of the entiremachine excepting the air-pump. The valve-chambers are shown in section.,Fig. 2 is an end view of the faucet. Fig. 3 is a cross-section of thefaucet on the line X Y, Fig. 2. Fig. 4 is a view of the faucetstop-plug. Fig. 5 is a crosssection of the stop-plug, taken on the lineX Y, Fig. 4. Fig. 6 shows several views of the rubber check-valve. Figs.7 and 8 are top views Figs. 9 and 10 are vertical sectional views of thevalve-chambers. Fig. 11 shows three views in section of the faucet,taken on theline X Y, Fig. 2.

Similar letters refer to similar parts throughoutthe several views.

The construction and arrangement of my improved beerforcing apparatusare as follows:

A represents the air-accumulator, which is made of sheet-iron,galvanized by preference.

the pipe K is usually fitted a strainer.

draulie air compressor or pump. Such a pump is shown and described inPatent No. 262,157, 4 dated August 1, 1882.

The air compressor and accumulator may be located at any convenientplace. From the accumulator the air is carried by the pipe 0 to thefaucet D, which faucet is supposed to be connected to an ice-box or'someother suitable place. The faucet D is constructed with .60 threepassages, O, G, and H, to the stop-plug E. (See Figs. 2, 3, and 11.)

The air-pipe G is connected to the center passage, 0. The pipesK and Damconnected to passagesG and H. The stop-plugE is con-' structed with anopening, a. This opening communicates with a vertical opening, 1).(Shown by dotted lines in Fig.. 4.) The stopplug E is also constructedwith a recess, cl. The passages G and H of the faucet D are connected bypipes K and L to the keg W,which keg may be located at any convenientplace. The pipe K is constructed to enter through a hollow plug, M, andcontinues down to nearly the bottom of the keg. To the bottom end of Thepipe L is connected to the hollow plug M,and made to communicate withthe inside top of keg W. The other end of pipe L is connected to faucetD at the passage H.

Connected to each of the pipes O, K, and L are valve-chambers J, S, andP. These chambers may be made of iron tubing. The heads It may be madeof cast=iron and screwed in the ends of the tubes forming the chambers.The pipes O, K, and L, connecting the chambers, may also be screwed intothe heads B. One part of the pipes is extended into the chambers fartherthan the other. On this extension is cut a screw-thread, and on this isscrewed a vulcanized rubber tube, V. This rubber tube is prepared in amanner that it will have a tendency to flatten and close. One end ofthis tube V' is screwed on the pipe extending into the chamber, and maybe tied bya linen thread, so as-to make it air-tight on the pipe. Theother end of the tube will flatten IOC press tight together the flatends of the tube, so as to make them air and water tight one way. Thepipe 0 is provided with one of these check-valves, to prevent beer fromgetting in the accumulator A in case the pressure in the accumulatorgets below that in the keg.

The pipes K and L are connected by a unionjoint, 0, Fig. 1, and thepipes G and K are provided with stop-cocks N and N.

To the upper end of pipeK may be arranged a coil, which may be locatedin an ice-box, to keep the beer cool. In place of an automatic air'punipa hand-pump may be used.

The operation of myimproved beer-forcing apparatus is as follows: Theaccumulator A is supplied with air and kept at a uniform pressure, whichpressure will be according to the height and distance the beer is to beforced. The pipes K and L being connected to the keg, as shown in Fig.1, the stop-cocks N and N are then opened. The handle of the plug Eoffaucet D is turned, as shown in Fig. 1, and also indicated by dottedlines in Figs. 3 and 11, marked Beer. This position of the stopplug Ecauses the air-pipe O to communicate, through recess (1 in plug E, withair-pipe L, and it carries the air down through theplug M into and ontop of the beer in keg WV, and the air-pressu re will force the beer upthrough pipe K and passage G of the faucet D and out of the openings (4and b of the stop-plug E. If the handle of the faucet be turned to theright, as indicated by dotted lines, marked Closed, the flow ofbeer'will stop, but the passages C and H will be opened to andcommunicate, so as to allow the air-pressure to continue on, the beer inthe keg. If. the handle be turned to the extreme right-to the dottedlines marked Reversed-that will close the passage H and connect thepassages O and G with the air-accumulator, and the airpressure willdrive back the beer in pipe K to the check-valve chamber P, when the gumvalve in that chamber will be closed by the back pressure. This willprevent the beer from being forced to the bottom of the keg, and it willbe forced through the pipe F into chamber S and through the lower partof pipe L into and upon the top of the beer in the keg W. The valve V inchamber S prevents the beer from rising in pipe L. When the beer hasbeen driven back into the keg or barrel, the air will fill the pipe Kand lower part of pipe L, and the air-pressure will be kept on the topof the beer in the keg until it is desired to draw beer again, when thefaucet is turned for Beer, as before described.

Having thus described the construction and operation of my in vention,what I claim as new, and desire to secureby Letters Patent, 1s

1. The combination of air-accumulator A, pipe 0, faucet D, having threepassages, C, G, and H, stopping E, having openings a b and recess d,pipes K and L, with chambers P and S, and tubular valves V, as shown,described, and for the purpose specified.

2. The combination of a beer-vessel, a valvechamber, an inlet and outletpipe, with a tubular gum valve to prevent the return of air or liquids,and a separate pipe leading from the valvechamber to the beer-vessel, asshown and described.
